## Summary

A court has heard that marine engineer Stephen Sexton apologised to his girlfriend’s sister after she found Joanna Derkacz dead at the couple’s home in Waterlooville, Hampshire. Arleta Derkacz said Sexton looked frightened and was holding a kitchen knife; prosecutors allege he had strangled her sister after a year of controlling and coercive behaviour.

In a recorded police interview played to jurors at Winchester Crown Court, Arleta described Sexton denying that Joanna was at home before she went upstairs and found her body. Prosecutors also allege Sexton contacted sex workers shortly after the killing. He denies murder, rape and controlling or coercive behaviour; the trial is continuing.
